UNITED STATES PATENT, OFFICE.

SYDNEY MILTON TOO'IAL, OF BLACKPOOL, ENGLAND."

Patented Feb. 8, 1921.

To all whom it may concern:

Be it known that I, SYDNEY MILTON TOOTAL, a British subject, residing at-Blackpool, county of Lancaster,-England, have invented certain new and useful Improvements in Dyes, of which the following is a specification.

This invention relates to improvements in dyes more particularly applicable for dyeing on a small scale articles such as silk or wool blouses and other garments.

Such garments frequently have an insertion of lace and when dyed at home the lace is also dyed or stained which gives to the garment a re-dyed appearance.

The present invention consists in employing for coloring matter weakly acid dyeing dyestufi's such as xylene red, xylene blue, ketone green, acid violet, acid orange II, acid red, roccellin, rhodamin B, magenta phosphin or other colors capable of being applied in a weak acid bath, in combination with a gelatinous substance such as gelatin or glue, and a weak organic acid such as acetic acid, tartaric acid, citric acid, or' formic acid to force the actlon of the dyestufi' directly on to the silk or wool and at the same time resist the action on the cotton.

In one form of the invention the followinrr combination is employed:

Vater 6 qts.

Coloring matter up to 10%.

Acetic, tartaric, citric or formic acid up t 5%.

Gelatin 20 lbs.

The whole is heated on a water bath the acid being added after the gelatin and coloring matter is in solution. The whole is then run into molds or trays and cut up after drying into squares or other shapes sufficient to dye a garment.

- witnesses.

Application filed April 22, 1920. Serial No. 375,770.

When necessary a solve t such as glycerin or acetin can be employed for the dyestuff.

A dye so formed can be readily used in any household and no boiling is required, the gelatin or glue acting as a resist to prevent any dyeing or staining of the insertion lace.

What I claim as my invention and desire to seeure'by Letters Patent is 1. A dye for dyeing articles composed of silk and cotton or wool and cotton which will not affect the cotton-consisting of the combination with a weakly acid dye stuff,

a gelatinous substance and Weak organic acid to force the action of the dye stuff on to the silkor wool.

2. A dye for dyeing articles composed of silkand cotton ,or wool and cotton which will not affect the cotton consisting of the combination with a weakly'acid dye stuff, a gelatinous substance, a weak or anic acid to force the action of the dye stu on to the silk or wool and a solvent for the weakly acid dye stufi'.

3. A dye for dyeing articles composed of silk and cotton or wool and cotton which will not aifeot the cotton consisting of the combination with a weakly acid dye stuff, a gelatinous substance, and solution of tartaric acid to force the action of the dye stuff on to the silk or wool.

In testimony whereof I have hereunto set my hand in presence of two subscribing SYDNEY MILTON TOOTAL.
